Yes, top 50 in points per month to see your ranking in speed/percentage. If you're in the top 100, you'll be on the points chart, which will let you look at your % and speed. Otherwise, check out the "My Scores" tab and click on the "This Month" over your personal stats chart. It won't show rankings, but you can see your time, %, # of games attempted/completed, and accumulated points. (Not in that order.)

Iltquilt, I see you at #66 in the monthly 100. You don't qualify at the moment for the speed & percent competitions, but your stats are in there. Hope that answers your question.
